Authentication error while trying to trigger a microflow with a button

0
Hello,  i am trying the tutorial from Mendix “Learn to build an sap app” and at step 5.1.1 I get the error CE1571 at my button with which I want to trigger the microflow. I don't understand what the problem could be as I have actually selected an argument for SalesOrder as shown in the picture. Are there any possible solutions?

Hello Denis,

 

Can you edit the button properties and see what you can select there :

Good luck!

Your screenshot shows the microflow button below the datagrid. Put it in de datagrid toolbar, so when the user selects a row the button can then be clicked with the selected CAUFV as parameter. Or put the button on the right inside the dataview.

You can do what Martin says.

Or depending on your mendix version you can add it yourself through an argument, however this is less logic to understand, but if you button really needs to be there at that spot it is possible.

principally i can display the data from sap in the dataview and datagrid, so in my opinion it cannot be due to the authentication right?

Hey Martin, i have found out that when I set the breakpoint at “Show page” in my microflow this error occurs. That means the problem should be within the Get entry. However, I have set it up as in the tutorial. Could it be because I am already accessing the SAP data in my first Microflow? or does it not matter?
